Fig 1.
Schematic overview of the torso (A) and lower extremity (B) including dissection planes of the cadaveric specimen. Red lines indicate the dissection planes. The access sheath is indicated in green. Fluid leakage is prevented by ligation of the main collateral arteries in the dissection plane, and, in the torsos, by balloon occlusion of the proximal aorta and ligation of the contralateral femoral artery.
Fig 2.
Cannulation of the femoral artery of a lower extremity.
A 7Fr sheath is used to create antegrade access of the lower extremity through the vacant femoral artery (white arrow) in the axial dissection plane.

Unenhanced CT of frozen lower extremity of a human cadaver.
The vein and artery are indicated with an arrow with ‘A’ and ‘V’ respectively. Differentiation between arterial lumen, vascular wall and calcifications are possible.
